Thanks in advance. As we know, vmalloc and other memory allocation/de-allocation will change/update the swapper_page_dir maintain by the kernel. I am wondering when/how the kernel synchronzie the change to user level processes' page directory entries from the 768th to the 1023th. Those entries get copied from swapper_page_dir when a user process get forked/created. Does the kernel frequently update this information every time when the swapper_page_dir get changed? Regards, Mike
